I'll ask my ophthalmologist about scleral lenses or maybe hybrid or K-rose lenses as some other comments mentioned.
There is more and more evidence to support the fact that KC is purely induced by eye rubbing.
Don't rub your eyes !
For a complete argumentation and discussion about the case for the role of eye rubbing in keratoconus genesis, please look at this website : https://defeatkeratoconus.com/
(Disclaimer: I work closely with one of the main proponent of the eye rubbing hypothesis. However, please believe that I don't have any conflict of interest in this topic. I don't have anything to gain in raising awareness about this problem, except feeling that I'm doing something right)
